| Source name |
Liver_ChIPSeq_Tead_LSL_7d
|
| Organism |
Mus musculus |
| Characteristics |
strain background: C57BL/6
genotype: ROSA26-rtTA-IRES-EGFP; tetYAP
tissue: liver
treatment: doxycycline food for 7 days
chip antibody: TEAD (Aviva Systems Biology, ARP38276)
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
For ChIP experiments, whole cell extracts were sonicated to solubilize the chromatin. The chromatin extracts containing DNA fragments with an average size of 250 bp were immunoprecipitated using different antibodies. For TEAD, dissected liver/tumors were fixed with 1% formaldehyde. For YAP ChIP, fixation was performed by a double step approach with 0.5 M DSG (Di-(N-succinimidyl)-glutarate) and 1% formaldehyde (FA).
For ChIP seq, libraries were prepared for Illumina sequencing using a standard protocol consisting in blunting, addition of dA overhangs, ligation of Illumina adapters, selection on gel and PCR with index primers.

Read filtering with fastx toolkit version 0.0.13.2: fastq_masker -Q33 -q 20 -r -N -v
Alignment to mm9 with bwa version 0.6.2; bwa aln -t 16 reffile fastqfile| bwa samse -n 1 reffile - fastqfile | samtools view -q 1 -ut reffile - |samtools sort - bamfile
Replicates of the same condition were merged after alignment to a single BAM file for the analyses
Peak calling was carried out with MACS version 2.0.9; macs2 -t samplebam -c inputbam --mfold=7,30 -g mm -p 0.00001
the input alignment file was randomly downsampled to the size of the ChIP sample alignment file
Input for peak calling was taken from GSE83863 published data
Genome_build: mm9
Supplementary_files_format_and_content: *_peaks.txt files: bed files of transcription factors; *.bw.gz: compressed bigWig files
